| Interference Potential Current has been one of the better companies as it relates to interference. They've been running the Cincinatti trials which have done well; they tend to stay out of amateur radio bands and in general avoid HF bands. Other vendors like Amperion and Ambient have had less than stellar interference track records. TXU had dumped an Amperion trial earlier in the year due to interference.
A ten year deal is pretty aggressive. This will make or break some decisionmaker's career at TXU  | |

DS2's Radio Friendly BPL Technology puts Competition on the Defensive
Speaking at 2005 UPLC Annual Conference, Victor Dominguez, DS2's Director of Strategy and Standardization, outlined the reasons why DS2's 200Mbps powerline solution is the only regulatory compliant technology available for BPL commercial deployments.
Dominguez was dismissive about claimed alternatives to DS2.
Mr Dominguez was adamant about competitors claims "I think that we have put the competition on the defensive. Our competitors would love to have the flexible notching capabilities that we have for BPL and In-Home PLCs, but the truth is that they don’t. DS2 has had dynamic notching since its first chip set and can mitigate radio interference in a programmable way and other PLC chipsets do not. We would like to thank our competition for the rumours propagated at several press interviews, they have been attracting attention towards one of the main competitive advantages of our technology, we mastered programmable notches in a 200 Mbps chipset more than 2 years ago, since then we have been shipping in volume for BPL and In-Home applications, and still remains to be proven that competition can follow us.”
DS2's technology is well known in the BPL industry for being one of the first proponents of programmable notching in powerline communications, as the best method for addressing potential interference to radio services. DS2’s 200 Mbps BPL technology, available in silicon since 2003, already implements this dynamic notching functionality, which has been tested in the field, in several commercial BPL deployments, and demonstrated in several BPL industry trade shows.
“Other competing technologies have some notches, but they are fixed, including the most advanced designs from followers (on top of that they exhibit performance below 40% our speed). This means that they fall short for the demands of regulators and consumers everywhere from the FCC to the European Commission who require that frequency bands can be selectively notched out, even after the equipment has been deployed. Operators deploying non-DS2 based solutions risk having their equipment withdrawn from the field because once it is out there, there is nothing that can be done to prevent interfence with radio signals. With DS2, however, any issues can be resolved even when the equipment is in the field by remotely disabling problematic frequencies thus complying with today's or future regulatory requirements and automatically avoiding any radio signals in any part of the world". Mr Dominguez placed special emphasis on the radio friendliness of the system.

| Re: Interference to ham radio operators? Hmph... First off, there are rules to this.
Have you ever tried to ask him about it? Most are very helpful with interference issues (unlike the CB crowd.)
If he tells you go screw yourself, then make a complaint to the FCC noting his name (if you have it), address, call sign (if you know it), and times and types of interference. They will ask him to rectify the situation or he will lose his license.
HOWEVER, if you do not work with him AT ALL, then your chances of getting it resolved are very slim.
And if you don't think the FCC takes action against those who interfere with the airwaves, guess again:

Hams are your friends if you talk to them. I'm a ham and have good relations with my neighbors. If I interfere, I fix the problem, regardless if it's their problem under FCC rules. You'll find most hams are the same, although I get the feeling you've never talked to one or met one. | |

| said by BigMac777 :Most Ham Radio operators do not care about there neighbors. ... HAM operators are not your friends period. You sound like someone I know. You live in Utah instead of Arizona? Are you the person who sued a co-worker of mine because he was a (censored) ham who interfered with her TV show and she had proof because she heard him say his name on the TV?
Only problem was 1. He put up the antenna and left the radio at his mother's just to see if that would happen, and 2. He worked low power (less than 10 watts) code, not high power (greater than 500 watts) voice. She still complains about his interference to this day and he has not been active for 5 years due to personal issues.
On a personal note, I have a ham about 3 houses away who runs HF SSB at about 100 watts. I know I heard him so I talked to him and we worked to find the problem. Turns out one of the ground wires for the AC power system ground in my house had corroded and was mixing his RF signal with another RF signal(s) and re-radiating on the TV frequency. Of course it helps that he had a spectrum analyzer, I am an electronics engineer, and neither of us have a blind stereo-typing mindset and blame the other for being a stupid idiot. Most hams keep their signal within the bands that are allotted for them, if not, the FCC does slap them down, and other hams will help them (there is a special group of volunteers who actually help do that).
And no, I do not have a HF transmitter and the only antenna on my house is the one for the TV (no cable). (well, I USE to have a CB radio which is HF, but because of the idiots now using CB radios, I sold it)
If you think you have a ham neighbor that is splattering your TV and is telling you to 'shove it', than call 888-CALL-FCC (225-5322) or write fccinfo@fcc.gov. Be prepared to give dates, times, call signs, what it was, what you were listening to, and what did you do to help work out the issue. Keep a good log, you will need it.

| RE:Interferance to Ham Radio Operators Moonpuppy, I beg to differ. If you send a complaint to the FCC regarding interference from a Ham Operator to your consumer electronic equipment, two things will happen. 1)the Ham will get a letter noting the problem and asking him/her to make sure the Ham station is in proper working order and 2) the complainant will get a letter explaining that if the station is in proper working order then it is up to the CONSUMER to apply corrective filtering devices on their consumer electronic equipment and they will get a link to the FCC website article which explains how to go about this and to contact the manufacturer of the equipment for assistance.
»www.fcc.gov/Bureaus/Compliance/N···5009.txt
»www.arrl.org/tis/info/rfigen.html
This is because the vast majority of consumer electronics has no RFI filtering and plastic cases (cabinets) that provide no protection. Every time someone proposes a RFI standard for consumer gear it gets shot down by the consumer electronics lobby, as the manufacturers don't want to provide the filters/better designed equipment due to a few dollars per unit saved by them.
If you meant the Gerritsen case by the reference to the second notation in your link, this has nothing to do whatsoever with interference to TVs or any other consumer electronics. He has for years deliberately interfered with Amateur, business and public safety transmissions, including after his license was revoked. Previous fines and jail time didn't stop him either.
Probably not what you wanted to hear but this is the way it works.

| Re: RE:Interferance to Ham Radio Operators said by TODDRICK :Moonpuppy, I beg to differ. If you send a complaint to the FCC regarding interference from a Ham Operator to your consumer electronic equipment, two things will happen. Todd Most Amateur Radio Operators (and I am excepting a few ornery characters I have known) are considerate of their neighbors, after all, Hams don't want interference either, as have co-exist in the same neighborhood - preferrably without tar and feathers.;).
Living with crappy consumer electronics can be done, but it's not easy. I have lived at this location now for 20+ years, and during that time I have operated extensively on HF and VHF with power levels from a few milliwatts to the maximum power allowed. In all that time, I have not had a single interference complaint. And all the neighbors know who I am, what I do for a hobby, and where I am - after all, it's hard to miss the 65 foot high tower in the back yard and the tri-band beam on top f it. (Well, it WAS, at least until Katrina came through!) Heck; I even enlisted their help to erect my antennas!
Good engineering practices and common sense can eliminate almost all the interference should it appear. Keep your transmitted signal clean, use a properly installed antenna, and uses the minimum power necessary for effective communications, and make sure you don't interfere with your own consumer electronics.
However, in some cases, you run across a piece of real consumer electronics JUNK that nothing - and I mean NOTHING seems to fix. One neighbor near my previous home had a cordless phone that heard everything from Hams to CB'ers and commercial stuff. The only fix for that was for them to replace it.
I also once bought a brand name VCR that turned out to be a fantastic receiver on 160 meters - if I fired up my transmitter with more than one watt, it would curl up and die. After a lot of testing and trying to clean up the interference, I simply tossed it in the trash and bought a different brand.
You can't win 'em all, but you can try!

| I think moonpuppy is a ham, so he probably agrees with you. While I agree the Gerritsen case isn't relevant to interference to consumer electronics, I think it does show that the FCC enforces the rules that are on the books, at least in regards to amateurs. If an amateur had a spurious emission in violation of Part 97 and that was causing interference (as opposed to shoddy consumer electronics design), you can bet the FCC would apply enforcement action, unlike what some others have said in this forum. | |

DING DING DING!! WE HAVE A WINNER!!!! 
Fact is, consumer electronics are made so cheaply, that interference is almost a forgone conclusion. Quality be damned, get it out to market so we can make a dollar. Remember the old ATT desk phones that could probably survive being dropped off a building? Now, just breathe on a new phone wrong and it dies. 
And you are right, the Gerritsen case shows that not only will the FCC enforce the rules BUT will go after you, with teeth, if you keep on breaking the rules.
Look a bit deeply and you will find other enforcement actions including unlicensed operation of Amateur equipment, improper use of GMRS equipment, intentional interference complaints, etc.
And, yes, I am a HAM. | |

| RE: Interferance to Ham Radio Operators Hello again, I really should have directed my earlier post to several people instead of singling out Moonpuppy. The Gerritson commentary is the only part really directed at him. The rest should have been directed at BigMac777.
RF Engineer is correct, the FCC will and does enforce our rules and regulations. If someone is operating and causing intentional interference or refuses to clean up a dirty signal they deserve to be hung out to dry. In the instance of unintentional interference from a properly installed and operated station, I recall the FCC siding with the Ham (would have to search the ARRL website to find articles). I don't think I can remember reading that the FCC imposed 'quiet hours' on someone with a properly operated station (I have only had my ticket for 22 years but was interested and was a SWL for 20 years before that) much less pulling their ticket. Most of the enforcement activity I remember has been unlicensed or otherwise illegal operation, RFI remediation aimed at electric power companies or electric fence owners and retests for those with suspicious exams/upgrades.
Hope this clarifies a bit, was pressed for time before and wasn't composing well.

HAMS, as a group, are required to adhere to guidelines that make us responsible for our stations and how they operate. We have to watch where we transmit (frequency wise), how we transmit (what modes, power levels, etc.) and how we communicate (no "10" codes, secret codes, foul language, etc.)
We do our best, for the most part, to live within the spectrum we are gievn and not to cause issues with neighbors. (I wonder if BIGMAC777 has a CBer and not a HAM across the alleyway? Good luck with him if he is a CBer. )
Consumer electronics have to follow Part 15. However, with more and more people wanting cheaper and cheaper electronics, costs do get cut and so do corners.
BTW, I know a group of guys that are on VERY good terms with Riley Hollinsworth.
